Indra OPMET Technology
Since 2011, when the 1st Meeting of the WMO Commission for the Basic Systems Task Team on Aviation XML took place, we have been gradually involved in the development and testing of IWXXM 1.0/2.0. It can be used stand alone or included in the Indra Avitech SWIM Solution (OPMET Services). Transportation over AMHS is also possible.
The current message repertoire covers the full OPMET set of messages – which are METAR, SPECI, short/long TAF, and SIGMET encoded in XML/GML schema. It conforms to the ICAO Manual on Digital Exchange of Aeronautical Meteorological Information (Doc 10003-AN/503). We also focus on the research and development of XML/GML encoded OPMET messages and other aviation meteorological products to support MET exchange between civil and military meteorological organizations.
Unlike the traditional forms of ICAO Annex 3/WMO No. 49 products, IWXXM is not intended for direct use by pilots. Application software will be used for visualization.
